screw driver will help. Fig 2 shows the steam thermostat has been relocated and
thermowell for RTD sensor is exposed (marked with red arrow).

2)
Install the RTD sensor.
Caution
: the connection between the RTD and cable is very
fragile because of the small size and there is no strain relieve. To prevent the sensor from
breaking, install the sensor without unwrapping the cable (install it as the way it was
received). This will reduce the twist pulling force when screwing on the sensor. The
sensor can be tightened with a small wrench or pliers. It does not need to be very tight. If
you want make sure the sensor didn’t get damaged during installation, you can measure
the resistance of the sensor after installation. It should be in the 100 to 140 ohm range.
3)
Install the cable from SSR output to the gray and red connector. Fig 3 shows what it
should look like at this step.
